2019R1 mo_tf error connverting yolov3-tiny

[Trost__David]

I got the following error attempting to convert my custom single class darknet yolov3-tiny model. I have run the model in darknet and it works.  Any ideas?

Dear David, you didn't post your actual Model Optimizer command but are you sure you're passing in C:\Program Files (x86)\IntelSWTools\openvino_2019.1.087\deployment_tools\model_optimizer\extensions\front\tf\yolo_v3_tiny.json  for --tensorflow_use_custom_operations_config ? Please carefully study the following document.

Thanks !

Dear David,

Also X-referenced from another post, you need to upgrade Tensorflow also:

sudo -H pip3 install tensorflow==1.12.0 --upgrade

Thanks !
